Description

A kind of shaft-like work processing jig

Technical field

The utility model relates to automatic gear-box shaft-like work processing technique field, in particular to a kind of shaft-like work is controlled with processing Tool.

Background technique

See Fig. 6, one end of the part shaft-like work 1 ' in automatic gearbox of vehicles is milled with plane 1.1 ', and is drilled with drilling 1.2 ', when carrying out the processing in the plane and hole, the other end of shaft-like work is folded up in the Workpiece clamping head 2 ' of lathe, is then used One jig 3 ' being fixed on lathe holds the side processed, as shown in figure 5, being provided with one and axis on jig 3 ' The adaptable circular arc type bracket 3.1 ' of workpiece, shaft-like work support is in the bracket.Since metal fragment can be generated in process, These metal fragments can usually be fallen into bracket, when carrying out the processing of next shaft-like work, be will lead to workpiece and upwarped, and then make There is the plane of working process the verticality in the gradient and hole to fail, and product defect rate is high.

As it can be seen that the prior art has much room for improvement and improves.

Utility model content

Place in view of above-mentioned deficiencies of the prior art, the purpose of this utility model is to provide a kind of processing of shaft-like work to control Tool, can avoid metal fragment influences the machining accuracy of shaft-like work, advantageously reduces product defect rate.

In order to achieve the above object, the utility model takes following technical scheme:

A kind of shaft-like work processing jig, including the bolster being fixed on lathe, which opens along its length Equipped with a V-groove, the circumferential surface of two wall surfaces and shaft-like work to be processed of the V-groove offsets.

The shaft-like work processing jig further includes an air compressor machine；The bolster is provided in the axial direction with air inlet, institute State the wall surface of V-groove downside it is axially disposed have multiple ventholes, these ventholes are connected to air inlet；Air compressor machine passes through defeated Tracheae is toward air inlet conveying high-pressure air.

In the shaft-like work processing jig, there are two the air inlet opens up, it is separately positioned on two wall surfaces of V-groove Lower section, be provided with venthole on the downside of two wall surfaces of V-groove, these ventholes are connected to corresponding air inlet respectively.

In the shaft-like work processing jig, the inlet of the air inlet is equipped with a connection mouth, which uses It is connect in appendix.

In the shaft-like work processing jig, the both ends of the air inlet perforation bolster, one end far from connection mouth is set It is equipped with a dismountable plug.

In the shaft-like work processing jig, the plug includes threaded portion, shoulder and the force application board that front and back is arranged；Spiral shell Line portion is provided with external screw thread, and is threadedly coupled by the external screw thread with air inlet；Force application board is used to apply torque to plug.

In the shaft-like work processing jig, the two sides of the V-groove are each provided with several counter sinks, and bolster is by wearing The screw for crossing these counter sinks is fixed on lathe.

The utility model has the advantages that

The utility model provides a kind of shaft-like work processing jig, when use shaft-like work support bolster V-groove In, two wall surfaces of V-groove offset with the circumferential surface of shaft-like work, and V-groove is contacted with shaft-like work line, and axially position is more accurate, And the metal fragment that generates enters after V-groove the bottom that can fall into V-groove when processing, will not pad cell wall and shaft-like work it Between, therefore not will lead to shaft-like work and upwarp, so that metal fragment be avoided to influence the machining accuracy of shaft-like work, advantageously reduce product Fraction defective.

Specific embodiment

The utility model provides a kind of shaft-like work processing jig, to make the purpose of this utility model, technical solution and effect Fruit is clearer, clear, and the utility model is further described as follows in conjunction with drawings and embodiments.It should be appreciated that this Locate described specific embodiment only to explain the utility model, is not used to limit the utility model.

Please refer to Fig. 1-4, a kind of shaft-like work processing jig provided by the utility model, including the pillow being fixed on lathe Block 1, the bolster upper surface offer a V-groove 1.1, two wall surfaces of the V-groove and axis work to be processed along its length The circumferential surface of part offsets.

In use, shaft-like work support in the V-groove of bolster, two wall surfaces of V-groove with the circumferential surface phase of shaft-like work It supports, V-groove is contacted with shaft-like work line, and axially position is more accurate, and the metal fragment generated when processing enters meeting after V-groove The bottom of V-groove is fallen into, will not be padded between cell wall and shaft-like work, therefore not will lead to shaft-like work and upwarp, to avoid metal Clast influences the machining accuracy of shaft-like work, advantageously reduces product defect rate.

Further, the shaft-like work processing jig further includes an air compressor machine 2；The bolster is opened up along axial direction There is air inlet 1.2, the downside of the wall surface of the V-groove is axially disposed multiple ventholes 1.3, these ventholes and air inlet 1.2 connection；Air compressor machine passes through appendix 3 toward 1.2 conveying high-pressure air of air inlet.When adding for one (or multiple) shaft-like work of completion Working hour can blow toward air inlet, and pressure-air can spray from venthole, the metal fragment accumulated at slot bottom is blown away, and complete V The cleaning of type groove, is not necessarily to manual cleaning, and cleaning efficiency is high.

In the present embodiment, the air inlet 1.2 is separately positioned on the lower section of 1.1 two wall surfaces of V-groove, V there are two opening up It is provided with venthole 1.3 on the downside of two wall surfaces of type groove, these ventholes are connected to corresponding air inlet respectively.On the one hand Cleaning effect can be improved in the gas output that high pressure gas can be improved, and on the other hand, blows toward both direction, guarantee is attached to two Metal fragment on wall surface is blown away, and further increases cleaning effect.

Further, the inlet of the air inlet 1.2 is equipped with a connection mouth 4, which is used to connect with appendix 3 It connects, connects more convenient.

Preferably, see that Fig. 3, the air inlet 1.2 penetrate through the both ends of bolster 1, one end far from connection mouth 4 is provided with one Dismountable plug 5.It, can be with cleaning needle miscellaneous in venthole 1.3 when there is sundries to enter air inlet 1.2 and venthole 1.3 Object is pushed into air inlet 1.2, then removes plug, last that sundries is blown out toward air inlet conveying high-pressure air, scale removal process letter Folk prescription is just.

Specifically, seeing Fig. 4, the plug 5 includes threaded portion 5.1, shoulder 5.2 and the force application board 5.3 of front and back setting；Screw thread Portion 5.1 is provided with external screw thread, and is threadedly coupled by the external screw thread with air inlet 1.2；Force application board 5.3 is used for plug applied force Square.The plug is convenient to mount and dismount, sealed reliable.

Further, the two sides of the V-groove 1.1 are each provided with several counter sinks 1.4, and bolster 1 across these by sinking The screw of head bore is fixed on lathe.The mounting structure, which is connected firmly, to be not easy to loosen.

It is understood that for those of ordinary skills, can with technical solution according to the present utility model and The design of its utility model is subject to equivalent substitution or change, and all these changes or replacement all should belong to the protection of the utility model Range.
